Interior of cabinets

[Charcigar]

Any suggestions as to how best to "clean up" the interior of my '67 Safari's wood cabinets?I am beginning the re-finishing of the exterior this weekend,but not sure how best to tackle the insides.the wood there is all solid,but quite grimy and in some places,old Mactac or something like that,is peeling and flaking off the cabinet shelves.

I would like to paint them,I think.Just want a nice cleans surface for my cloths,food etc.

Would Zolotone be a good choice for this?

Any other suggestions?
